iOS (Jailbroken): If the multitasking tray on your iPad feels a little underutilized, TenIconSwitcher can help fill it out.

The tweak simply adds three additional app icons to the landscape multitasking tray, and four to the portrait version, bringing the total to ten. The result looks pretty nice in landscape orientation, but you might find it to be a little cluttered in portrait. Still though, it will often save you a swipe or two when trying to switch back to an old app.
